Optical axis tunable liquid crystal lens, electronic apparatus, display apparatus, and method of operating optical axis tunable liquid crystal lens

A method of operating an optical axis tunable liquid crystal lens, comprising:

• providing a liquid crystal lens comprising a liquid crystal layer, a control electrode, and a black matrix configured to define an aperture;
• the control electrode comprising a first electrode, a second electrode, and a central electrode on a side of the liquid crystal layer away from the first electrode, the first electrode is on a side of the liquid crystal layer away from the second electrode, the second electrode comprising a first sub-electrode and a second sub-electrode spaced apart from each other and being on two opposite sides with respect to a center of the second electrode, the first sub-electrode and the second sub-electrode being independently addressable, the aperture is in a position corresponding to the central electrode, an orthographic projection of the aperture on the liquid crystal layer covers an orthographic projection of the central electrode on the liquid crystal layer, and an orthographic projection of the black matrix on the liquid crystal layer covers an orthographic projection of the second electrode on the liquid crystal layer;
• applying a common voltage signal to the first electrode;
• applying a first voltage signal to the first sub-electrode;
• applying a second voltage signal to the second sub-electrode;
• and
• adjusting a relative position of an optical axis of the liquid crystal lens comprising independently adjusting a first voltage difference between the common voltage signal and the first voltage signal and a second voltage difference between the common voltage signal and the second voltage signal.
